Steps to Closing a Probate Estate?

Is it required during closing of an estate a signed release waiver of the admin/executor by the beneficiaries?

Generally, an estate is closed by the filing of an affidavit by the executor. Attached to it are releases from the division of taxation, department of human services, and, releases of the heirs at law. Your attorney should be able to assist you with the filing. If you are unrepresented you may want to hire an attorney to help wrap things up.
